Joystick module fills terminal with "SDL_JoystickGetAxis value:" #498

(current master, on Linux) Is there a way to prevent this ?

suz1 commented 6 years ago

OK I have found this is because of SDL (a game library) printing debug messages, some sites are saying this is a compile time option for SDL, with debug options leading to printing this message. I am looking for a workaround (either piping this to dev null or recompiling the SDL module not to do this) as I also would like this functionality - it messes up SITL testing with a joystick as the MAVProxy window (though still functional) is spammed. I've tried looking through the code, but it appears that although there seems an aspiration to have verbose and debug modes, these switches ('joystick set debug, joystick set verbose') haven't been implemented yet. If I can find a workaround I will post it here.

Ok solved. This problem is caused by a bug in pygame. You need at least version 1.9.3, in Linux this will not automatically install for me with pip install (I have 1.9.0 and the new version hasn't been updated). I followed the instructions at http://python-gaming.com/pygame/docs/install.html and successfully rebuilt pygame to 1.9.4dev, and these messages no longer appear but joystick input works.

Thanks! This bug annoys me any time I deal with the joystick stuff.
